- a model 200 is expressed by one or more rigid bodies.
- each part of the model 200 is expressed by a rigid body. Therefore, a displayed shape in the rigid body animation cannot have deformation, and locations of the vertexes included in the shape of the model 200 are fixed with respect to a predetermined reference point. Specifically, locations of the vertexes included in the shape of each part of the model 200 are fixed with respect to a predetermined reference point, for example, a center of gravity, of each part.
- the authoring unit 110 is adapted so as to create information on predetermined reference points of each part of the model 200 and locations of the vertexes with respect to the predetermined reference points.
- the model 200 is a human being having a head 212 , a trunk 214 , a left arm 216 , a right arm 218 , a left leg 220 , and a right leg 222 .

Specifically, locations of the vertexes included in the shape of each part of the model 200 depend on the movement of the bone of each part. Therefore, the authoring unit 110 for creating the skin/bone animation creates information on the location and orientation of the bone for each part of the model and locations of the vertexes relative to the bone.
- the model 200 includes a head 232 , a trunk 236 , a left arm 240 , a right arm 244 , a left leg 248 , and a right leg 252 .

- the locations of the vertexes included in the shape of each of the parts 236 , 240 , 244 , 248 and 252 depend on the movement of each of the bones 234 , 238 , 242 , 246 , 250 , or 254 for each respective part 236 , 240 , 244 , 248 and 252 , and the locations of the vertexes included in the shape of the part 236 , 240 , 244 , 248 and 252 are fixed with respect to the bones 34 , 238 , 242 , 246 , 250 , or 254 of each respective part 236 , 240 , 244 , 248 and 252 .
- every single vertex included in the shape of the model 200 is defined. Therefore, the authoring unit 110 for creating the morphing animation creates information on the locations of every single vertex included in the shape of the model 200 . In this case, information on the location of each of the vertexes included in the shape of the model 200 may be changed as time progresses.

- the animation reproduced by the animation reproduction unit 120 does not contain only one kind of content that has been initially set, for example, as in a movie or a live concert video.
- the animation reproduced by the animation reproduction unit 120 is an animation decided according to the result of the key manipulation of a user. For example, if a user instructs by key manipulation that the animation b 2 is to be reproduced while the animation reproduction unit 120 is reproducing the animation b 1 of the model B, the animation reproduction unit 120 starts to reproduce the animation b 2 . In this case, the animation reproduction unit 120 does not reproduce the animation b 2 just after the animation b 1 , but generates an intermediate animation b 1 ′ by blending the animations b 1 and b 2 in order to gradually change from a walking figure to a running figure.
- the original animations b 1 and b 2 are reflected in the intermediate animation b 1 ′ by predetermined proportions.
- the animation reproduction unit 120 generates and reproduces the intermediate animation b 1 ′ in such a way that the proportion of the original animation b 1 reflected in the intermediate animation b 1 ′ is gradually reduced as time progresses. Accordingly, the animation reproduction unit 120 starts to reproduce the animation b 2 when the proportion of the original animation b 1 reflected in the intermediate animation b 1 ′ becomes 0%. Operations of the animation reproduction unit 120 will be described below in more detail by exemplifying operations of the restoration unit 122 through the display unit 140 , particularly, through the motion blending unit 134 .

- One or more compressed animations may be input to the restoration unit 122 in a sequential manner one by one, or a set of compressed animations may be simultaneously input together.
- the storage unit 124 temporarily stores the restored animation, and may function as a type of cache. Specifically, an animation that has been previously restored at least one time is stored in the storage unit 124 . As a result, it is not necessary for the restoration unit 122 to repeatedly restore the animation that has been previously restored.
- a compressed or uncompressed animation may be provided to the animation reproduction unit 120 .
- the animation created by the authoring unit 110 may be provided to the animation reproduction unit 120 via the compression unit 112 or without passing through the compression unit 112 .
- the storage unit 124 stores the animation.
- the motion decision unit 126 decides the desired motion to be reproduced by the animation reproduction unit 120 according to the result of the key manipulation input through the input terminal IN 1 .

- a personal computer PC
- keypads on a keyboard provided with the PC a wired or wireless mouse connected to the PC, a joystick wired or wirelessly connected to the PC, or a touch screen provided in the PC may function as the interface.

- the decided motion may be one of a walking and a running motion, or a mixture of a walking and a running motion having proportions of 20%: 80%.
- the motion decision unit 126 decides the desired motion such that the motion can be visually recognized as being continuous over time when the result of the key manipulation requires a change of the reproduced animation. For example, if a user instructs, by means of the key manipulation, the animation reproduction unit 120 to reproduce the animation b 2 while the animation b 1 is being reproduced, the animation reproduction unit 120 sequentially changes the proportions between the running and walking figures in order to gradually change the motion of the model from the running figure to the walking figure.
- the motion decision unit 126 may decide the blending proportions between the running and walking figures to be sequentially changed in the following order: (100%:0%) ⁇ (90%:10%) ⁇ (70%:30%) ⁇ (50%:50%) ⁇ (30%:70%) ⁇ (10%:90%) ⁇ (0%:100%).
- the motion determination unit 126 may determine that the motion of a currently-reproduced animation is appropriate or no operation is necessary.
- the motion decision unit 126 notifies the search unit 128 , which will be described below, about the decided motion. At the same time, the motion decision unit 126 may also notify the blending unit 134 , which will be described below, about the decided motion.
- the search unit 128 searches the storage unit 124 for at least one animation corresponding to the desired motion. For example, if blending proportions between the running and the walking of the decided motion are 70%:30%, the search unit 128 searches the storage unit 124 for the animations b 1 and b 2 . If the determined motion is the walking motion, the search unit 128 searches the storage unit 124 for the animation b 2 .

Abstract
Description
- This application claims the benefit of U.S. Provisional Patent Application No. 60/719,562, filed on Sep. 23, 2005, in the U.S. patent and Trademark Office, and Korean Patent Application No. 10-2006-0039553, filed on May 2, 2006, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
- 1. Field of the Invention
- The present invention relates to animation reproduction, and more particularly, to an animation reproducing method and apparatus for generating and reproducing an animation corresponding to a desired motion by blending one or more previously provided animations according to the motion even when the animation representing the desired motion is not previously provided.
- 2. Description of the Related Art
- When a user plays a 3-dimensional (3D) graphic game using a personal computer (PC), animation data is usually prepared in the PC for each model and each motion beforehand. For example, if a motion of a model M having a human shape is controlled by a user on a journey to a specific destination in the game, two kinds of animation data m1 and m2 of the model M may be prepared in the PC beforehand, where m1 is an animation representing a running figure of model M, and m2 is an animation representing a walking figure of model M.
- In this case, a user decides what kind of animation data will be reproduced by manipulating keys provided in the PC. For example, if a user instructs the PC to reproduce a running figure m1 of the model M, by manipulating the keys while the animation data of the walking figure m2 is being reproduced, the PC starts to reproduce the animation data of the running figure m1.
- When the animation data to be reproduced is changed in the conventional animation reproducing apparatus as described above, a user may visually recognize that the motion of the model M is discontinuous and changes in an unnatural manner. As a result, the conventional animation reproducing apparatus has a problem in that the motion is unnatural when the kind of animation data to be reproduced is changed. Moreover, such a problem becomes more serious as the number of kinds of animation data that have been previously prepared is small.

model 200 is expressed by one or more rigid bodies. In other words, each part of themodel 200 is expressed by a rigid body. Therefore, a displayed shape in the rigid body animation cannot have deformation, and locations of the vertexes included in the shape of themodel 200 are fixed with respect to a predetermined reference point. Specifically, locations of the vertexes included in the shape of each part of themodel 200 are fixed with respect to a predetermined reference point, for example, a center of gravity, of each part. Accordingly, theauthoring unit 110 is adapted so as to create information on predetermined reference points of each part of themodel 200 and locations of the vertexes with respect to the predetermined reference points. In this case, the information on the predetermined reference points may be changed as time progresses while the information on the locations of the vertexes with respect to the predetermined reference points always remains constant. Referring toFIG. 2A , themodel 200 is a human being having ahead 212, atrunk 214, aleft arm 216, aright arm 218, aleft leg 220, and aright leg 222. The shape of each part includes a plurality of vertexes. The vertexes may constitute a plurality of polygons such as a triangle. As shown inFIG. 2A , locations of the vertexes included in the shape of thehead 212 are fixed with respect to a predetermined reference point, for example, a center of gravity of thehead 212. This can be similarly applied to thetrunk 214, theleft arm 216, theright arm 218, theleft leg 220, and theright leg 222. Furthermore, relative positions of each part of themodel 200 are also fixed. For example, a relative position of thehead 212 with respect to thetrunk 214 is always fixed. - In the skin/bone animation, it is supposed that each part of the
model 200 includes a certain skeleton system such as bones, and movement of each part depends on movement of the bone associated with that part. The shape of themodel 200, i.e., locations of the vertexes of the skin depends on the movement of the bone. Specifically, locations of the vertexes included in the shape of each part of themodel 200 depend on the movement of the bone of each part. Therefore, theauthoring unit 110 for creating the skin/bone animation creates information on the location and orientation of the bone for each part of the model and locations of the vertexes relative to the bone. In this case, information on the location and orientation of the bone can be changed as time progresses, while information on the locations of the vertexes relative to the bone is always constant. Referring toFIG. 2 b, themodel 200 includes ahead 232, atrunk 236, aleft arm 240, aright arm 244, aleft leg 248, and aright leg 252. The shape of each part includes a plurality of vertexes. Eachpart bone FIG. 2B , locations of the vertexes included in the shape of thehead 232 depend on the movement of thebone 234 included in thehead 232. However, the locations of the vertexes included in the shape of thehead 232 are fixed with respect to thebone 234 of thehead 232. The locations of the vertexes included in the shape of each of theparts bones respective part part bones respective part - In the morphing animation, every single vertex included in the shape of the
model 200 is defined. Therefore, theauthoring unit 110 for creating the morphing animation creates information on the locations of every single vertex included in the shape of themodel 200. In this case, information on the location of each of the vertexes included in the shape of themodel 200 may be changed as time progresses. Referring toFIG. 2C , themodel 200 includes ahead 262, atrunk 264, aleft arm 266, aright arm 268, aleft leg 270, and aright leg 272. In this case, theauthoring unit 110 defines all the locations of the vertexes included in the shape of eachpart - The
compression unit 112 compresses the animation and outputs the result of the compression to theanimation reproduction unit 120. For example, a file resulting from the compression may have an extension “.sab”. - The
animation reproduction unit 120 reproduces the animation. The animation reproducing apparatus according to the present invention is implemented by theanimation reproduction unit 120. Theanimation reproduction unit 120 includes arestoration unit 122, astorage unit 124, amotion decision unit 126, asearch unit 128, amotion blending unit 134, ananimation supply unit 136, arendering unit 138, and adisplay unit 140. - The animation reproduced by the
animation reproduction unit 120 may be the rigid body animation, the skin/bone animation, or the morphing animation. - The animation reproduced by the
animation reproduction unit 120 does not contain only one kind of content that has been initially set, for example, as in a movie or a live concert video. The animation reproduced by theanimation reproduction unit 120 is an animation decided according to the result of the key manipulation of a user. For example, if a user instructs by key manipulation that the animation b2 is to be reproduced while theanimation reproduction unit 120 is reproducing the animation b1 of the model B, theanimation reproduction unit 120 starts to reproduce the animation b2. In this case, theanimation reproduction unit 120 does not reproduce the animation b2 just after the animation b1, but generates an intermediate animation b1′ by blending the animations b1 and b2 in order to gradually change from a walking figure to a running figure. Thus, the original animations b1 and b2 are reflected in the intermediate animation b1′ by predetermined proportions. Theanimation reproduction unit 120 generates and reproduces the intermediate animation b1′ in such a way that the proportion of the original animation b1 reflected in the intermediate animation b1′ is gradually reduced as time progresses. Accordingly, theanimation reproduction unit 120 starts to reproduce the animation b2 when the proportion of the original animation b1 reflected in the intermediate animation b1′ becomes 0%. Operations of theanimation reproduction unit 120 will be described below in more detail by exemplifying operations of therestoration unit 122 through thedisplay unit 140, particularly, through themotion blending unit 134. - The
restoration unit 122 restores the compressed animation input from thecompression unit 112. For example, a file having an extension “.m3d” would be a result of the restoration. One or more compressed animations may be input to therestoration unit 122 in a sequential manner one by one, or a set of compressed animations may be simultaneously input together. - The
storage unit 124 temporarily stores the restored animation, and may function as a type of cache. Specifically, an animation that has been previously restored at least one time is stored in thestorage unit 124. As a result, it is not necessary for therestoration unit 122 to repeatedly restore the animation that has been previously restored. - A compressed or uncompressed animation may be provided to the
animation reproduction unit 120. In other words, the animation created by theauthoring unit 110 may be provided to theanimation reproduction unit 120 via thecompression unit 112 or without passing through thecompression unit 112. Even when the uncompressed animation is provided to theanimation reproduction unit 120, thestorage unit 124 stores the animation. - The
motion decision unit 126 decides the desired motion to be reproduced by theanimation reproduction unit 120 according to the result of the key manipulation input through the input terminal IN1. In this case, the key manipulation input functions as an interface capable of reflecting a user's intention as an electrical signal. For example, when a personal computer (PC) is provided with theanimation reproduction unit 120, keypads on a keyboard provided with the PC, a wired or wireless mouse connected to the PC, a joystick wired or wirelessly connected to the PC, or a touch screen provided in the PC may function as the interface. - The decided motion may be selected from those represented by one or more animations that have been previously prepared, or may be selected from motions other than those represented by one or more of the previously-provided animations. For example, the decided motion may be one of a walking and a running motion, or a mixture of a walking and a running motion having proportions of 20%: 80%.
- The
motion decision unit 126 decides the desired motion such that the motion can be visually recognized as being continuous over time when the result of the key manipulation requires a change of the reproduced animation. For example, if a user instructs, by means of the key manipulation, theanimation reproduction unit 120 to reproduce the animation b2 while the animation b1 is being reproduced, theanimation reproduction unit 120 sequentially changes the proportions between the running and walking figures in order to gradually change the motion of the model from the running figure to the walking figure. For example, themotion decision unit 126 may decide the blending proportions between the running and walking figures to be sequentially changed in the following order: (100%:0%)→(90%:10%)→(70%:30%)→(50%:50%)→(30%:70%)→(10%:90%)→(0%:100%). - When there is no key manipulation, or when the key manipulation does not require a change of the reproduced animation, for example, as in a pause or a restart, the
motion determination unit 126 may determine that the motion of a currently-reproduced animation is appropriate or no operation is necessary. - The
motion decision unit 126 notifies thesearch unit 128, which will be described below, about the decided motion. At the same time, themotion decision unit 126 may also notify theblending unit 134, which will be described below, about the decided motion. - The
search unit 128 searches thestorage unit 124 for at least one animation corresponding to the desired motion. For example, if blending proportions between the running and the walking of the decided motion are 70%:30%, thesearch unit 128 searches thestorage unit 124 for the animations b1 and b2. If the determined motion is the walking motion, thesearch unit 128 searches thestorage unit 124 for the animation b2. Thesearch unit 128 includes aninspection unit 130 and areading unit 132. Operations of thesearch unit 128 will be described hereinafter in more detail. - The
inspection unit 130 inspects whether or not the animation stored in thestorage unit 124 corresponds to the decided motion. The animations stored in thestorage unit 124 may be preferably managed using a least-recently used (LRU) method. In other words, theinspection unit 130 inspects the least-recently used animation in advance. Alternatively, the animations stored in thestorage unit 124 may be managed using a most-recently used (MRU) method. In other words, theinspection unit 130 may inspect the most recently searched animation in advance. - If the inspection determines that there is a stored animation corresponding to the decided motion, the
inspection unit 130 generates and outputs a reading-out control signal. Thereading unit 132 reads the stored animation corresponding to the decided motion from thestorage unit 124 and outputs the read animation as a searched animation in response to the reading-out control signal. - When the inspection as to whether or not there is any animation corresponding to the decided motion in the
storage unit 124 is completed for all of the stored animations, theinspection unit 130 inspects whether or not there is any animation which corresponds to the decided motion and is not included in one or more of the searched animations. - If it is inspected that there is an additional animation which corresponds to the decided motion and is not included in the searched animations, the
inspection unit 130 generates and outputs a restoration control signal. In this case, therestoration unit 132 operates in response to the restoration control signal. That is, therestoration unit 132 performs restoration for the compressed animations that have been input from thecompression unit 112 but have not yet been restored, in response to the restoration control signal. - The
motion blending unit 134 operates when a user instructs, by means of key manipulation, that the reproducing animation is to be changed. In this case, themotion blending unit 134 blends one or more searched animations according to the decided motion. Specifically, themotion blending unit 134 multiplies each of one or more searched animations by a weight value corresponding to the decided motion, and adds the results of the multiplications. -
FIG. 3 is a schematic diagram for describing operations of themotion blending unit 134 ofFIG. 1 . Referring toFIG. 3 , a user instructs, by means of key manipulation, that the animation b2 be reproduced at a time point t1. Theanimation reproduction unit 120 does not start to reproduce the animation b2 from a time point t1 (t=t1) but starts to reproduce the animation b2 from a time point t2 (t=t2, where t2>t1). Themotion blending unit 134 generates an additional animation by blending the animations b1 and b2 by predetermined proportions during a time period t1<t<t2. For example, themotion blending unit 134 may generate the additional animation using a formula b1×1.0+b2×0.0 at a point of time ta (t=ta), using a formula b1*0.9+b2*0 at a point of time tb (t=tb), using a formula b1*0.7+b2*0.3 at a point of time tc (t=tc), using a formula b1*0.5+b2*0.5 at a point of time (t−td), using a formula b1*0.3+b2*0.7 at a point of time te (t=te), using a formula b1*0.1+b2*0.9 at a point of time tf (t=tf), and using a formula b1*0.0+b2*1.0 at a point of time tg (t=tg), where t1<ta<tb<tc<td<te<tf<tg<t2. - The
animation supply unit 136 receives the result of the blending from theblending unit 134 after themotion blending unit 134 operates. Similarly, theanimation supply unit 136 receives the searched animation from thereading unit 132 when theblending unit 134 does not operate. - The
animation supply unit 136 supplies the received animation to therendering unit 138. In this case, the received animation may be the result of the blending or of the searched animation. Therendering unit 138 renders the animation supplied from theanimation supply unit 136. Here, the rendering refers to a type of visualization. - The
display unit 140 displays the result of the rendering. A liquid crystal display (LCD) may be implemented as thedisplay unit 140, for example. -
FIG. 4 is a flowchart for describing an animation reproducing method according to an embodiment of the present invention, which includesoperations 410 to 420 of generating and reproducing an animation corresponding to a desired motion by blending one or more previously-provided animations according to the desired motion even when the animation representing the desired motion is not previously provided. - The
motion blending unit 134 blends one or more of the previously-provided animations according to the desired motion to be displayed on the display unit 140 (operation 410). In this case, a previously-provided animation is an animation created in theauthoring unit 110. More specifically, the previously-provided animation is an animation searched for by thesearch unit 128 as a desired animation corresponding to the motion to be displayed. - After
operation 410, therendering unit 138 renders the result of the blending performed inoperation 410 and displays the result of the rendering (operation 420). -
FIG. 5 is a flowchart for describingoperation 410 illustrated inFIG. 4 according to an embodiment of the present invention, which includesoperations 510 to 540 for blending one or more of the previously created animations according to a desired motion. - The
restoration unit 122 restores one or more compressed animations (operation 510), and thestorage unit 124 stores the animations restored in operation 510 (operation 520). - The
search unit 128 searches for one or more animations corresponding to a desired motion that is to be displayed, among the animations stored in operation 520 (operation 530). - After
operation 530, themotion blending unit 134 blends one or more animations searched for inoperation 530 according to the desired motion that is to be displayed (operation 540). -
FIG. 6 is a flowchart for describingoperation 530 illustrated inFIG. 5 according to an embodiment of the present invention, which includesoperations 610 to 630 of searching for the animation corresponding to the desired motion among the animations stored inoperation 520, andoperation 640 of determining whether or not there is an animation which corresponds to the desired motion and is not included in the searched animations. - The
inspection unit 130 determines whether the animation stored inoperation 520 corresponds to the desired motion (operation 610). - If it is determined that the animation stored in
operation 520 corresponds to the desired motion inoperation 610, thereading unit 132 determines the stored animation to be the searched animation. - After
operation 620, theinspection unit 130 determines whether there is an animation for whichoperation 610 is not performed among the animations stored in operation 620 (operation 630).Operation 630 may be performed afteroperation 620 is performed, as illustrated inFIG. 6 . Alternatively,operation 630 may be performed beforeoperation 620 or simultaneously withoperation 620. - Meanwhile, if it is determined that the animation stored in
operation 520 does not correspond to the desired motion inoperation 610, the process proceeds tooperation 630. - If it is determined that there is an animation for which
operation 610 is not performed inoperation 630, the process proceeds tooperation 610. - If it is determined that there is no animation for which
operation 610 is not performed inoperation 630, theinspection unit 130 determines whether there is an animation which is not included in one or more animations determined inoperation 620 and corresponds to the desired motion to be displayed (operation 640). - If it is determined that there is an animation which is not included in one or more animations determined in
operation 620 and corresponds to the desired motion, the process proceeds tooperation 510. If it is determined that there is no animation which is not included in one or more animations determined inoperation 620 and corresponds to the desired motion, the process proceeds tooperation 540. - The invention can also be embodied as computer-readable codes on a computer-readable recording medium executable by a computer. The computer-readable recording medium is any data storage device that can store data which can be thereafter read by a computer system. Examples of the computer-readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, floppy disks, optical data storage devices, and carrier waves (such as data transmission through the Internet). The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer-readable code is stored and executed in a distributed fashion.
- As described above, in the animation reproducing apparatus and method according to an embodiment of the present invention, an animation representing a desired motion is generated and reproduced by blending one or more previously-provided animations according to the desired motion even when an animation corresponding to a desired motion is not previously provided. Therefore, it is possible to reproduce even a new motion which does not exist among the motions expressed by one or more previously-provided animations. As a result, an animation reproducing method and apparatus according to the present invention can enable the desired motion to be realistically and naturally reproduced by changing the reproduced motion until it becomes a different motion even when the desired motion is entirely different from the currently reproduced motion. Meanwhile, in the animation reproducing apparatus and method according to an embodiment of the present invention, since even a compressed animation can be restored and reproduced in a real-time manner, it is possible to reduce a burden on a storage space which is necessary for the previously provided animations. Furthermore, in the animation reproducing apparatus and method according to an embodiment of the present invention, since the restored animation can be temporarily stored, the stored animation can be reproduced promptly.
- While the present invention has been particularly shown and described with reference to embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. The embodiments should be considered in descriptive sense only and not for purposes of limitation. Therefore, the scope of the invention is defined not by the detailed description of the invention but by the appended claims, and all differences within the scope will be construed as being included in the present invention.
